Marcus Smart was subdued, a stark contrast to the outburst that sent shock waves through Oklahoma State's basketball program hours earlier.

Smart was suspended for three games Sunday by the Big 12 for shoving a fan in the closing seconds of the Cowboys' loss at Texas Tech on Saturday night. The conference said in a statement that the All-America guard showed "inappropriate conduct with a spectator."

Smart, a sophomore, apologized to the fan, his teammates and his family for the altercation.

"This is not how I conduct myself," said Smart, a top NBA prospect. "This is not how the program is run. This is not how I was raised. I let my emotions get the best of me."

Late in Saturday night's game in Lubbock, Texas, Smart tumbled out of bounds behind the basket after trying to block a shot. He was helped to his feet and then shoved Jeff Orr with two hands after it appeared the Red Raiders fan said something to him. Teammates pulled Smart away.

Texas Tech released a statement saying it conducted a thorough investigation. Orr denied making a racial slur, and Tech said the evidence backs Orr's statement.

Orr, who goes to many Texas Tech games, agreed to not attend any Red Raiders home or away games for the rest of the season.

Smart will miss games against Texas, Oklahoma and Baylor.
